The most prescient portrait of the American character and our ultimate fate as a species is found in Herman Melville’s “Moby Dick.” Melville makes our murderous obsessions, our hubris, violent impulses, moral weakness and inevitable self-destruction visible in his chronicle of a whaling voyage. He is our foremost oracle. He is to us what William Shakespeare was to Elizabethan England or Fyodor Dostoyevsky to czarist Russia.
